Good choice. I really think that's all you need. It's really good advice above to pick up a cheap but good prime, too. Even the Pentax A 50mm f./2 is no slouch, despite some people having a grudge against it. It's slightly slower, 1/3 of a stop, but it's like $20 - and you can control its aperture from the camera.
Also, don't be afraid to stop down if the light allows. You seem to want a lot of depth of field, so stopping down to f./16 or so can really help with that. Just watch that your shutter speeds don't drop too much, or you'll get soft results due to camera shake.
